Supplement to Prospectus

The following information supplements the Prospectus of The Prudential Series
Fund, Inc.:
DETERMINATION OF NET ASSET VALUE
Short-term debt obligations with a maturity of 12 months or less held by the
Conservative Balanced Portfolio and Flexible Managed Portfolio are valued on an
amortized cost basis in accordance with an order obtained from the Securities
and Exchange Commission. Each of the Portfolios must maintain a dollar-weighted
average maturity for its short-term debt obligations of 120 days or less. The
values determined by the amortized cost method may deviate from market value
under certain circumstances. The Board of Directors has established procedures
to monitor whether any material deviation occurs and, if so, will promptly
consider what action, if any, should be initiated to prevent unfair results to
Contract owners. The short-term portion of these Portfolios may be invested only
in high quality instruments, as described in the Prospectus.
